'llhis application has for its object to provide mechanism for receiving sheet glass from an intermittent forming machine, and.

atter the severing by a transverse cut of such sheet into plates of appropriate length to pernnt them to be fed sidewise into a lehr, to

transport the several plates formed by such severing opposite the mouths of several lehrs, To accomplish these purposes the mecha nism illustrated in the accompanying drawings comprises an interm ttent forming machine of any approved construction, adapted.

' plates, and means for independently advancing each carriage as the glass thereon is severed from the glass on the following carriage (and preferably at. a higher rateof speed than that of sheet formation) to opposits the mouth of the lehr served by such carriage. The invention claimed herein con sists in the arrangement and combination of the several parts above named, and of-the driving instrumentalities therefor and in the as) construction of such parts and instrumentalities as will be hereinafter more fully described and claimed. I By a special arrangement and construction of t e carriages ot' the train, as will be'rnore fully described hereafter it is provided for, that, it suitable, the rounded front end of 1 the sheet of glass can be severed and also that the rounded rear end of the sheet together with the chilled residue left at the completion of the forming operation can be v received on a special carriage attached to the, rear 10'? the train of carrlages, if this rear Figures 2, 2, 2*, and 2* arefvertical lon- T929.

Figures 3, 3*, 3? and 3 are planviews of track parts corresponding to Figures 2, 2, 2 and 2; and

1-4 are the rolls of an intermittent torming machine, preferably but not necessarily, of the type shown in the iUnited States patent M) to Bicheroux, No. 1,573,098, and adapted to form from molten glass a sheet whose length maybe several times its brea th.

The frame 2 of this forming machine straddles tracks 8, the lower roll 1. being at some as distance above the tracks, A series of glassreceiving carriages at, d", a, travel upon the tracks and beneath the "forming rolls to receive the glass sheet, formed at the pets between the rolls as the same issues therefrom, m the sheet being guided between the pass and the carriages by the inclined apron 5. In the drawings, three carriages are shown, but ohviously this number may be increased or also decreased. v5

The carriages in moving beneath the rolls to receive the sheet are connected together by couplings 6, each coupling; comprising a latch 6 pivoted to the carriages in advance and adapted to engage a pin 6* on the followan ing carriage, this engagementbeing normally maintained by a spring 6 but being at times broken by the tail 6 oi the latch striking an inclined ramp 7 located along the track past the position of the forming machine.

There is a-gap 8 between the lass-receiving surface of each carriage an the glass-=- receiving surface of the adjacent carriage,

- and there is a gap 8 in the surface of the first carriage 4 adjacent to the forward end to 7 thereof. The arrangement can also be, that instead of the gap in thesurtace of the first carriage, a s ecial advance carriage is coupled ahead 0 the first carriage and then there is agap between the first carriage and the $95 advance carriage, exactly as between two other adjoining carriages. In this case the first carriage has the same length as the other carriages.

Alongthe trackway, adjacent to, but be- 10 yond the forming machine, is located the severing mechanism, consisting of glass cutting knives 9 adapted to descend and to enter the gap 8 in the carriage t to sever the head of the sheet, and to enter the gaps 8 to sever the glass on the one carriage from the glass on the adjacent carriage, the knives descending as the carriages move along. Details of such severing mechanisms and of the actuating means therefor are not shown herein because they are described and shown in United States Patent No. 1,765,552. The rear carriage is also short as it is intended to receive the rounded training end formed on the sheet (this as well as the forward end of the sheet being rejected), and is provided with a glass receiving pit 10 into which the cold glass or cullet remaining in the forming machine after the fabrication of the sheet may be deposited.

The several carriages carry depending toothed section 11, the several sections on the several carriages, when the latter are connected, together forming two continuous racks.

Gear wheels 12 located between the tracks, and. intermediate of the forming machine and the point where the adjacent carriages are uncoupled by the ramps 7', mesh with the rack sections 11 of the carriage located thereover,

and moves such carriage and carriages coupled therewith forward at approximately the speed of sheet formation. The geanw eels are driven, by any suitable mechanlsm by which they may be stopped and reversed 1n rotation.

Located in a pit near one end of the track is a. series of drums 13 13 (one drum for each carriage, exec t the last one and eventually except the a Vance carriage) with appropriate drive mechanisms 14:, 14c therefor, the drives being through clutches 15, 15. provided with brakes 16 16". Av cable 17 17 is driven by each drum. Gne run of each cable passes over guide pulleys 18, 18 and is attached to a lever 19, 19 of the corre sponding carriage, the other run of the same cable being carried over a sheave 20 20 to the opposite end of the track where it passes over suitable take-up mechanism 21, 21 and is then laid back between the, tracks and is attached to a'second lever 22, 22 pivoted on the same carriage. The levers 19*, 19", and 22 are connected to sliding links 23 having stop collars 24 (see Fig. 2), by which the movement of the levers is limited, and provided with cushioning springs 25 to take up jar in starting and stopping the carriages.

Along the track beyond the forming machine and arranged side by side lengthwise of the track are a series of lehrs, represented diagrammatically in Figure 1, at 26 and 26", each lehr being appropriated to one of the sheet-receiving carriages and adjacent to the tracks are arranged spring pumpers 27 (Fig. 2), adapted, by engaging staggered proaeeaaoa jections on the several carriages to arrest them opposite the several lehrs correspond ing thereto.

In the device as above constructed, the operation is as follows:

With the parts shown in the positions illustrated in the several figures, glass is fed to the forming machine and the rolls 11 of that machine put in motion, if they do not already rotate. As the head of the sheet feeds from the apron onto the forward section of the first carriage r, the train of carria es is also put in motion by starting rotation o the gears 12, thereby the cables are carried along with the carriages and drive the drums 13, 13 while the clutches 15?, 15 are slipping. The speed of movement of the table at this time will be about the speed of sheet formation, say 0.3 meters per second, and as the train of carriages progresses past the position of the knives 9 the latter descend and sever the glass sheet into plates as is described in the Patent No. 1,765,552.

The first severing is between the head section of the first carriage and the following part of the same carriage respectively between the advance carriage and the first carriage, and merely serves to cut off the rounded end of the glass, if suitable. The successive s'everings are between the several carriages and serve to cut the sheet into a plurality of. plates. Shortly after the knife has descended behind the first carriage to separate the glass on it from the glass on the rest oi the train. the lever 6 of the coupling between the first carriage and the second carriage strikes the ramp 7 and unlocks the two car riages. At this time the operator closes the clutch 15, driving the cable appropriated to such first carriage. The cable is now driven at a substantially higher speed than was the train of carriages by the gears 12, say, at the rate of 1.7 meters per second. The first carriage therefore moves away from the train and rapidly assumes a position opposite the lehr 26 which is appropriated to such carriage, and 18 arrested in its motion by the bumper 27. The operator at the same time opens the clutch 15 and applies the brake 16 to quickly stop the cable. This operation is repeated for each carriage as the knife descends behind such carriage.

Considering now each succeeding carriage. except the cullet carriage 4, it will be mdved forward by its appropriate cable at a speed Intermediate of the speed of travel oi the tram as a whole and the high speed of movement of the preceding carriage, until it comes opposite a lehr appropriated to it and located between the lehr of the first carriage and the forming machine. Thus the several portions of the sheet are brought opposite their respective lehrs at a uniform time after the formation of that portion ofgithe sheet, which time is selected with a view of permitting the insertion of the sheet into the lehr at the time best for that purpose. The plates on the several carriages are then shoved ofi thfi several carriages into the corresponding 1e r.

The quantity of glass fed to the forming machine can be so selected that the' tail end of the sheet is deposited on the last carriage, which has been stopped as soon as the glassreceiving pit 10 arrived underneath the inclined apron 5.

After the plates upon the several carriages have been shoved into their respective lehrs, the drums 13, 13 are reversed in rotation and the cables feed the several carriages rearwardly. 'The carriage in advance of the end carriage 4 strike the forward end of that carriage and moves it rearwardly until its rack section engage with the gears 12. The con- .tinued movement of these two carriages brings the lever 6 of the coupling between them past the ramp 7 andthe'carriages are locked together by the coupling. As each succeeding carriage is moved back to contact with the one preceding it, this locked action is repeated until the carriages have resumed the position shown in Figs. 2 and 2 and are locked together ready to receive a new sheet of glass.
